Traditionally, Gaussian assumption, implied by the Wiener process, is widely admitted for modeling degradation processes. However, when data exhibit heavy tails, this assumption not suitable. To overcome limitation, article proposes a novel class of tail-weighted multivariate model, which built upon Student-t process. The model able to account both between-unit variability and process dependency, while allows adjusting tail heaviness through tuning parameter degree freedom. For reliability...
Progressive-stress accelerated life testing (PSALT) is a special type of experiment that tests the lifetime product with continuously varying stress levels. Due to limitations equipments and costs, data collected by PSALT are usually censored have group effects. In order deal two characteristics in data, this paper presents novel model effects under progressive censoring. Two-stage Gauss-Hermite quadrature methods proposed estimate parameters, while interval estimates constructed bootstrap...
In industry, many highly reliable products possess multiple performance characteristics (PCs) and they typically degrade simultaneously. When such PCs are governed by a common failure mechanism or influenced shared operating environmental condition, interdependence between these arises. To model dependence, this article proposes novel multivariate reparameterized inverse Gaussian (rIG) process model. It utilizes an additive structure; that is, the degradation of each marginal PC is...
